Popis: Abstract Purpose The NY‐ESO‐1 antigen is highly immunogenic and often spontaneously induces an immune response in patients with cancer. We conducted a large‐scale multicenter cohort study to investigate the utility of serum NY‐ESO‐1 and p53 antibodies as predictive markers for the postoperative recurrence of gastric cancer. Here, we examined the usefulness of pre‐treatment NY‐ESO‐1 and p53 antibodies as tumor markers for the diagnosis of gastric cancer in combination with carcinoembryonic antigen (CEA) and carbohydrate antigen 19‐9 (CA19‐9). Methods A total of 1031 patients with cT3‐4 gastric cancer were enrolled in the study. NY‐ESO‐1 and p53 antibodies were assessed prior to treatment. The positivity of NY‐ESO‐1 and p53 antibodies, CEA, and CA19‐9 was evaluated before treatment. Results Serum NY‐ESO‐1 and p53 antibodies were positive in 12.6% and 18.1% of the patients, respectively. Positive NY‐ESO‐1 antibody response was correlated with male gender, higher cStage, and upper tumor location. However, a positive p53 antibody response was not associated with tumor factors. The combination of NY‐ESO‐1 or p53 antibody response with CEA and CA19‐9, or the 4‐factors, was positive in 45.1%, 49.6%, and 53.8% of patients, respectively. Moreover, the 4‐factor combination was able to detect >60% of cStage III‐IV diseases, which was 14% higher than that with the combination of CEA and CA19‐9. Conclusion The combination of NY‐ESO‐1 and p53 antibody responses to CEA and CA19‐9 increases the diagnostic accuracy of gastric cancer. Serum NY‐ESO‐1 and p53 antibodies may be useful tumor markers for gastric cancer.
